In the law of the Westminster system a major tenant of fair play is the use of equal force in defense. But then we see circa 200,000 civilians killed by coalition forces against 3,000 Americans killed on 911. Then we see 40,000 civilians killed (so far) in Gaza by Netanyahu against circa 300 killed by Hamas.

So, not only does this dynamic create a huge imbalance of Western law and moral inequity, but it also creates a far greater potential for the justification of revenge.
